To all whom it may concern:

Be it hown that T, DANJDEL hf. WRIGHT, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Diein -Machine, of which the following is a speci cation.

My invention relates especially to that class of machines in which two dies are brought together to form to predetermined shape a device located between them, such machines being designed to exert great pressure of the dies one upon the other, and which machines are commonly designated by shop terms as power presses, and an object of my invention, among others, is to pro vide a machine 'of this class that shall be particularly steady and eficient in its opera tion, and one embodying in its structure a minimum amount of metal with a maximum amount of strength.

One form of machine embodying my invention, and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view in vertical section through the machine on plane denoted by dotted line 11 of Fig. 2.

Fig. 2 is a view in vertical section through the machine on plane denoted by dotted line 2-2 of Fig. 1.

The dies employed in dieing machines commonly have cooperating surfaces one of which usually comprises a matrix, and it is, therefore, essential that such dies shall be moved one toward the other in right lines and without other movement, as if such other movement takes place the dies will not properly register and they, therefore, become quickly dulled or worn out. This objectionable movement may be very slight, to produce the injurious results above de scribed, and in fact the spring of the metal of which the frames of the machines are constructed may be sufficient to cause this treme steadiness in the movement of the dies is obtained and with practically no move floor to be readily accessible by a Workman,

and the frame comprising the ends, cross bars and table preferably being composed of a single piece of metal cast to shape. @penings 9 are formed through the ends and boxes 10 are secured to the under side of the table in position to support a main driving shaft 11 that projects through said opening and has a driving pulley 12 loosely supported on its outer end, and being adaptedfor connection with the shaft by means of a clutch 13. This clutch may be of any well known form of construction whereby, upon downward movement of the treadle 14 by the foot of the operative, the rod 15 is drawn downwardly and the clutch parts are operated to connect the driving pulley or fly wheel with the shaft, and upon one com- Elete revolution of the shaft the clutch will e automatically disengaged from the driving pulley, the latter being usually driven as by means of a belt.

The shaft 11 is provided with a crank 16 the end of the rod being journaled upon a pin 19 secured within said support. The rod may be provided with any ordinary means for changing its length, as an adjusting screw 20 having threads of did'erent character on opposite ends fitting within sleeves 21 and 22 journaled upon the crank 16 and pin 19 respectively. A flange 23 upon the screw is provided with suitable means to receive a spanner wrench by means of which it may be turned, and lock nuts 24!: are employed to secure the screw. against accidental turning movement, in addition to bolts 31 extending through the. split sleeves 21 and The cross bars 7 are provided at opposite ends with steps 25 within which guide openings extending through the steps and into the cross bars are formed, and guide posts 26 projecting from the support 1d extend into these openings and erve as a means for lid lid

llllllli llld - gular form when viewed in plan, said columns, of any desired number, extending through the table 8, the openings through which being preferably formed and equipped to receive the columns and guide their movements therein. As shown in the drawing the posts-26 and columns 27 are formed as to one set of each, of a single piece or rod extending through the support and secured by the aid of nuts on opposite sides of the support. A die holder 28 is secured to the upper ends of the columns and bears a die 29 positioned to cooperate with the die 30 on'the table 8.

It will be readily appreciated that the wei ht of my improved machine is located at t e bottom thereof and below the lower die. The dies are located and move substantially in the line of application of power transmitted from the support 18 to the die holder 28, so that there is no chance for any tipping or lateral movement of either of the dies, and the frame is so constructed that there can be no springing of the metal in this application of power whereby the dies may be caused to get out of alinement to any extent.

The table supporting the dies being located at the top of the machine, the work is exposed to full light and the workman may readily see what he is doing. The adjustment of the dies becomes a particularly simple matter and the chances for injury to the workman are thus greatly reduced. The machine, therefore, has the highest eificiency in the performance of work requirin the application of immense power in mac ines of this class.

In accordance with the provisions of the patent statutes, I have described. the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means.
